Just out of interest, with the Blade front sight do yiou use a 6O'clock hold or hold on the point you want to hit.

With a bead and peep I tend to cover the point of aim but with a blade I go to a 6 o'clock hold.

Graeme has some formular that he uses to work out what hight front sight you need. I found his findings to be out a fair margin he may well be working off a longer or shorter barrel.

I should have a couple more front sights in green here shortly. Graema is still working on a way to get Lothar Walther barrels out of Germany.
